Title: Improvements in or relating to method and apparatus for continuously forming elongated shapes from thermoplastic materials
IPC: B29C48/10
Filed: 1952-12-02
Abstract: 723,730. Automatic pressure control. POLYMER CORPORATION. Dec. 2, 1952 [Aug. 6, 1952], No. 30525/52. Class 38 (4). [Also in Group V] In a method of forming elongated shapes of uniform size from softened or liquified thermoplastic material in which the material is fed by a screw feed mechanism to a forming device, the speed of rotation of the screw feed mechanism is so controlled as to establish and maintain a substantially uniform pressure of the material at the inlet end of the forming device to ensure uniformity of size of the shape being formed. An extrusion cylinder 12 houses a screw 14 driven by a variable-speed electric motor 16 to force plastic material through a long forming tube 17. In a chamber 18 between the discharge end of the screw and the inlet to the tube is fixed a pressure-responsive bellows 51. The bellows communicates by way of an oil-filled line 52 with a Bourdon tube 53 arranged to shift an armature 54 in relation to windings 57 connected to a control circuit 58 coupled to the motor control unit 49. When the pressure in chamber 18 rises, the armature 54 moves and the motor slows down, whereupon the pressure drops, and vice versa. In a modification (Fig. 11, not shown) the motor is a constant-speed one and is connected to the screw through an adjustable clutch, e.g. a magnetic clutch adapted to vary the torque transmitted by variation of the current flowing through a rotor or armature; such variations of current being caused by variations of pressure on bellows 51.

Title: A driving mechanism for a windscreen wiper
IPC: B60S1/16
Filed: 1963-08-01
Abstract: 1,017,520. Windscreen wipers. NIPPON DENSO KABUSHIKI KAISHA. Aug. 1, 1963 [Aug. 10, 1962], No. 30620/63. Heading A4F. A driving mechanism for a windscreen wiper incorporating a device for parking the wiper comprises a worm 10, and worm gearing 11 which drive an eccentric shaft 1 and connected clutch plate 13, driving plate 18 and crankshaft 2, so causing crank-pin 5, to rotate with effective radius C-E and oscillate a wiper through a transmission rod. On parking the wiper, by depressing switch 22, Fig. 4 (not shown) electro magnetic coil 26 is energized and pulls down armature plate 28 with its connected cam plate 30. Part 31 of the latter then abuts projection 16 of clutch plate 13, till the clutch plate revolves 180 degrees when the cam plate 30 may drop down further. The clutch plate 13 continues to revolve, the projection 16 now sliding around the periphery of cam plate 30 so the whole clutch plate is displaced in the direction of the arrow X till projection 15 touches stopper plate 32 so stopping the rotation of the clutch plate. Simultaneously finger 14 is released from engagement with worm gear 11 so that crankshaft 2, driving plate 18 and clutch plate 13 stop rotating. The motor still drives gear 11 and shaft 1 however so crankshaft 2 carries out eccentric motion increasing the effective radius of the crank pin 5 to C+E to park the wiper. Just as this parking position is reached projection 15 abuts lever 20 which opens a contact to stop the drive motor and so prevent further oscillation of the wiper. At the same time electro magnetic coil 26 is deenergized so cam plate 30 is lifted by spring plate 29 to its original position. On restarting the wiper drive through switch 22, the eccentric shaft rotates, so rotating the crank pin 5 with a radius C+E until the clutch plate finger 14 under the action of a return spring engages with recess 12 when the crankshaft 2 also rotates to reduce the effective radius of rotation of the crank pin 5 back to C-E for normal wiping operation.

Title: Improvements in hand tools for cutting the sheaths of metallic sheathed electric cables
IPC: H02G1/12
Filed: 1949-11-29
Abstract: 670,829. Cable strippers. BRITISH INSULATED CALLENDER'S CABLES, Ltd., and BAKER, H. A. Nov. 28, 1950 [Nov. 29, 1949], No. 30642/49. Class 36. A hand tool for making circumferential and helical cuts in the metallic sheaths of electric cables comprises a body 1 into which the cable can be passed, carrying a cutting wheel 3 mounted in a plane at right-angles to the cable axis and adjustable into a plane making an acute angle with this plane, and a cable supporting member 11, which presses the cable against the cutting-wheel 3, mounted on the body so that it is adjustable towards or away from the cutting-wheel and can be withdrawn from the position in which it is adjusted against a biasing spring 17. The wheel 3 is mounted on a threaded spindle 4 which passes through holes in bracket 2 and strip 6 which project beyond the end of tube 1, so that the spindle cannot rotate relatively to the strip 6. This strip has a arcuate slot 8 through which a pin 9 mounted on bracket 2 projects so that the strip 6 and thus the spindle 4 can be rotated through about 30 degrees. A nut 7 locks these parts in position. A bracket 10, diameterically opposite the bracket 2 carries the supporting member 11 on which are mounted four rollers 12 with their axes lying in a semi-circle. The member 11 is carried by a rod 13 secured within an externally-threaded tube 14 by means of a nut 18. The tube 14 can be rotated within a threaded hole in bracket 10, thus adjusting the position of the support 11. To insert a cable within the tool a lever 19 mounted below the nut 18 is depressed, drawing the rod 13 up against the action of spring 17. After positioning the cable end within the body 1 the lever 19 is released, causing the support 11 to engage the cable and press it against the cutter 3. The cable is rotated to make a circumferential cut in the sheath and the angle of the cutter 3 then adjusted by means of strip 6 so that further rotation of the cable causes a helical cut to be made in the sheath, extending from the circumferential cut to the cable end. A metal rod 22 having a slot 23 is then withdrawn from the body 1 to the desired position and the end of helical strip formed on the cable sheath is inserted in slot 23. The tool is then rotated to strip the severed sheath off the cable.
